Ford used to know how to deal with this issue. I have two 2006 Escape Hybrid vehicles and they are still running and getting 26-30 mpg. There is a button inside the kick panel on the driver side. When you push that button, the 12V chassis battery can jump start the HiVoltage battery, which can then start the engine. Once the engine starts, the HiVoltage battery is recharged normally by the engine. I have used this feature multiple times for both vehicles. Unfortunately, the button was discontinued in early 2007. I was never aware of the reason for doing that. In a previous life, under license by GM, I manufactured reproduction batteries for 1955-1969 Corvette & Chevrolet. Therefore, I am acutely aware of liability exposure for any battery manufacturer. This may have had an impact on Ford's decision to remove the button. If my Escapes did not have this feature, they would have been scrapped long ago. I am sure their useful life has been extended by more than 100%.
At the time, Ford was known for how they charged the HV battery, assuring it was not overcharged and not allowed to be undercharged. The charge level was kept between 40% and 65%-so no undercharge or overcharge.

The attached pdf is from the 2006 Escape Hybrid Owners Manual.
